Time and time again, I've tried and switched out different pistols, and time and time again, I've returned to the same gun for carry: Gen 2 Glock 19, bought brand new in 1994, with Ranger or HST in the mag and new Trijicon HD sights. Carry it in a well-weathered and beyond comfortable Kramer horsehide paddle holster which was made by Greg back in the day when he ran his shop nearby, along with a single mag pouch.
I've wanted to try and fall in love with Kydex, so I recently bought a double mag pouch to try. So far, it's comfortable, but the jury is still out for me as to whether or not I want to try a Kydex holster. If and when I do, I'll have my friend who owns Northwest Tactical Products make a holster and mag pouch combo for me. I appreciate and support local craftsmen of the trade.
I also carry a Streamlight PT 1L flashlight and a Kershaw Blur daily. I have bigger, stronger lights, but for EDC, the Streamlight fits my needs well.
XDs just came back from recall and I need to put it through it's paces again before I decide to carry it. I bought it originally as a summer carry pistol and it carries and conceals well, but I have to figure out if it's better than the 642 which has been great for years. When I carry that, it's in a Mika Pocket Holster and yep, that holster is worth every penny and the praise it's given on this and other boards.
I always like reading these threads, even if they're a repeat every now and then. It's fun to hear about one's carry evolve over time and experience.
